The control determines the type of free cooling changeover based on which sensors are present and reliable. Conditions include the following items:

  • Operational space temperature and operational outdoor temperature = dry bulb changeover
  • Operational space temperature, operational outdoor temperature and operational outdoor humidity = single enthalpy
  • Operational space temperature, operational outdoor temperature, operational outdoor humidity, and operational space humidity = dual enthalpy
  • If the operational outdoor air temperature value is unreliable, free cooling is not available.
